Su Xin had learned various and sundry martial arts, but while he was teaching Lin Qing, he was also sorting out his own martial arts fundamentals.
He wanted to integrate dozens of martial arts into one. What Su Xin sought was the ultimate 'Way' that belonged to him. Regardless of what martial arts he would cultivate in the future, his unique 'Way' would never deviate.
What Su Xin taught Lin Qing was very simple. He did not teach Lin Qing any moves, he merely taught Lin Qing to forget any swordsmanship he had learned, and to defend against any method he used to strike with a sword.
Lin Qing, who was a bit slow-witted, found nothing wrong with the seemingly foolish teaching method. On the contrary, he was delighted.
As for Fang Qiaohua, a commoner, she could not discern anything. As long as she saw her son enjoying his sword practice with Su Xin every day, she felt content.
